-// Local functions are compiled to private static functions on the class
-// containing the local funtion. This has a number of consequences observable
-// from a debugging perspective, for this test specically:
-//   - local functions do not figure in the LVT of the outer function, as they
-//     are not instantiated.
-//   - the _declaration_ of the local function does not figure in the byte code
-//     of the outer function and hence, has no line number
